THANK YOU SOOOOOO MUCH!!!!!!!! When I study a very hard subject and do not understand ANYTHING, I watch your videos and you make it so easy to understand. BEST EDUCATION VIDEOS!!!!!!!!
Good easy to get explanation. I have a rare eye condition called optic nerve hypoplasia. It’s a plethora of things like endocrine issues developing Epilepsy and other things missing such as poor sense of taste or smell. Time and time again I’ve had to explain to medical people because they never heard of the condition with reference to other professional people in hopes that they will get it. Essentially a miscommunication between the pituitary gland and hypothalamus, but that’s not always present for every case of anyone with that eye condition. This video is another one to add to my list when I don’t feel like “explaining it again and again“ nowadays, everyone has a smart phone so in all fairness, they could self educate. That’s what my current neurologist said. Still grateful for the first one who focused more with Nuro ophthalmology who made the connection with, the types of seizures I was having and why.
Thank you. Extremely informative. Is it possible to have a lump within Brodmann 17 which could possibly be an electronic stimulator? Without changing my diet or exercise program have gone up and down in weight which made no sense. So many questions. But thank you for the lecture.
It detects markers in the blood and releases the appropriate hormones. For instance, if it finds that testosterone is too low in a nigga's blood compared to the baseline level, it will release GnRH, which will trigger LH and FSH production in the anterior pit gland, which will stimulate the dude's nuts to produce testosterone. As for bitches, it's just swapped with estrogen and ovaries. Fact up, curry nigga.
Hmmm. What are some of the different factors that can contribute to hormonal imbalances? Since the hypothalamus and the pituitary gland regulate so many hormones, why is it some people experience a deficiency or an excess of only some of the hormones rather than necessarily all of them when there is a hypothalamic or pituitary dysfunction? If the hypothalamus was, for example, not properly distributing GnRH and TRH, how would that affect the pituitary gland's release of FSH/LH and TSH?
This really makes me wonder if there is a connection between my high level of TSH...Hypothalamus constantly producing TRH to send to the pituitary to make TSH, and my neuropathic gut pain (visceral hypersensitivity) - pain generated in the hypothalamus. Interesting. Maybe when I start levothyroxine and TSH is normalised I will find out. Whilst this is not typical, it could be possible in my case.
hypothalamus communicating with the pituitary via the portal system would not be considered paracrine because of the utilization of the blood stream. This would be classified as endocrine signaling.
If i could upload a meme here, it would be the meme of that asian guy squinting at a piece paper because I CAN'T SEE ANYTHING (anyway, good content keep up the good work)
What I am keen to learn is the reason why or how the hypothalamus knows which hormone it should release. Fir example, I have learned that in body temperature regulation, if the blood going through the capillaries is either too hot or too cold, then the relevant nuclei in the hypothalamus respond by sending a message down to the veins to either dilate or constrict, to the skin to shiver or to sweat . So that heat is conserved or dissipated. I am interested to know how the hypothalamus recognises what the body needs and does depending on the outside stimulus in more detail. Cab anyone help? Many thanks For example, say someone saw somethung thar they found attractive. The image would enter through the eyes go to the optic nerve and back to the occipital lobe where the image would be interpreted as attractive. Then, it must somehow go from the outer cortex into the hippocampus and into the hypothalamus to release certain hormones in the pituitary which I imagine then kicks off the release of oxytocin hormones and others, in the body? But how does the hypothalamus detect oh my human perceives this image as attractive? If someone could help illuminate me I would be very grateful.
from the hypothalamus hormones travel to anterior pituitary through blood....... how could?? harmones from hypo thalamus travel through nerve fibres to the posterior pituitary ??
Why does the communication of the Hyothalamus and Anterior Pituitary through a portal system considered a paracrine secretion? Is it not endocrine? if not please explain to me, I'm confused. Thanks!
because endocrine signals are long distance hormonal signals ... the study of hormones was called endocrinology before autocrin and paracrin functions were found so it was to late to rename things
I agree it's too late to rename things, after all the medical world is constantly changing. Hence, books are constantly revised. paracrine is cell to cell communication, autocrine is to itself while endocrine is a communication via blood flow.
I am a little confused, because in the previous video (@ ua-cam.com/video/ER49EweKwW8/v-deo.html), it was written that the Hypothalamus will release ADH / Oxytocin, but in this video it is written that the posterior pituitary release ADH / Oxytocin. Can they be interchangeable??
Wait, how can it be that simple? What about how other regions affect the hptlms or the pituitsry or vice versa? When I hear prolactin, I think post nut clarity, bit also pro-lactin...sounds like estrogen to me. But I paused the video amd googled it...turns out estrogen inhibits prolactin, while dopamine induces it...and where does T come in all thst? The more you know, the less you know...god damn it...and how does all this manifest functionally? How can you talk about fsh without dht, is there a longer video on all this on your channel? I truly dig this khanacademy videos, but was a bit too reductionist, even for a lay simpleton like me...bit still, thank for for clarifying all those acronyms, I'm gonna gk make some notes now. Edit: Sry, I just saw a bunch of related videos in this topic delving deeper into many of those..
I like anabolic/androgenic steroids. Nandrolone is shit for sex drive!! Dianabol is great for sex but makes me aggressive when stacked with testosterone. Anadrol is anabolic but never makes me aggressive when stacked with testosterone!! *For your info
I thought GH from the pituiritary goes to the liver where it is converted into IGF1. Doesnt that mean that 'flat peg' is incorrect? Since GHis not a direct hormone then... Anyone who has the answer?
That is correct GH effect on growth is indirect as you said because it acts on the liver to increase IGF-1 production which acts an endocrine function. Further it acts on bone and other connective tissue to release IGF-1 as a paracrine factor. But GH has other direct functions on the liver. It acts on the liver to increases gluconeogensis, adipose tissue to increase lipolysis and on muscle to increase amino acid uptake and protein synthesis. So in terms of GH's growth actions it is indirect, but in terms of its metabolic effect it is direct. However, I think the reason it is classified as direct it is not acting on another endocrine gland (ex. TSH on thyroid). But it is important to realize that although classification systems are absolutely essential to medicine, they is a degree of arbitrariness in classifying things, and every classification system will have grey areas. But an excellent question as this is a more sophisticated detail about the ever complex endocrine system.
I think that you should definitely look into spiritual stimulation. Learn more about your body's chakras, and try to seek healing in them. That could help you quite a lot.
Èven tho the cause was an infection in the brain that basic ly killed them . The surgery was so radical it did so much damage. I will look into it thank you. You are the first person ever to care enough to say something so I thank you. It really sux living without a functioning pituitary gland or hypothalamus.
Oh my gosh, I'm so sorry.. Yeah that must be very hard to live with.. I know exactly what you mean, I had a very very big issue recently, and an islamic person was the only one to actually help me in my time of distress. We all gotta stick together in these tough times of life
Why are we even in school while we are literally you tube students 😁😁this is a saver👏
in you tube you see videos when you are ready for learning
@@Poonams586 exactlyyyyyy perfectly said! I love to learn this way
School is irrelevant nowadays lol
I know 😩 it’s too expensive especially considering how much I have to teach myself
Please be aware sir that your upload of this video is greatly appreciated. This was the exact information I was looking for. Have a lovely day.
THANK YOU SOOOOOO MUCH!!!!!!!! When I study a very hard subject and do not understand ANYTHING, I watch your videos and you make it so easy to understand. BEST EDUCATION VIDEOS!!!!!!!!
Dudes out here saving lives. Appreciate you man
6 minutes of knowledge that changes everything! 🙏
1000x thank you for this video. Really basic understanding is exactly what I needed today.

You just don't know how much this helped me!! Thank you!
You're Channel is helping me survive school!! thank you!
Me too!! It is a great basic science recap that makes understanding the clinical information much more effective.
Tarra Clark ok
Pavan Mehat ok
Hi baby 😂
Thank you so much! May God reward you
future nursing student here! bless your heart this is so helpful
Wow. Thank you so much you've made my assignment easy to understand
Thankyou so much sir. I needed to clear my concepts so badly and your video was just awesome.
Thnk u fr tus yputube. Ur Englush s too stylish @ gud. It helped me fr my entera exam. Keep Rocking always
so much info packed into 6 minutes!!!
10 years later. Thank you khan and the Tutor
Thank you soooooo much😢❤❤❤❤❤❤❤❤
Thank you for posting this educational video. I have Sheehans Syndrome and it can be a complex disease to understand. #HypoGal
Thank you soo much for sharing your knowledge with us . Blessings
you really save my day😊
This is a nice video. Ride on Sir
Beautifully illustrated! :)
good job explaining and making information clear.
BASHA THANK YOU !!!!!!!!!!!!!!!!
Khan academy is literally the best
Medical science is so cool when you come from the angle of Yogic and Body-mind science.
What do you mean? Can you give an example?
u gives us an easy way to learn all the things 😛😛😛😛
Ye emojis ki kya zaroorat thi?
I hope Vietsub will be available soon !!!
Helpful❤️
Amazingly explained!!
Isnt growth hormone tropic since it stimulates the liver to release IGF & IGFll?
Very Helpful...!! Thank you so much
No one:.....
Everyone: BRAINBALLS HAHAHAHAH
awesome... 😊💪💪👍👍
very helpful!!! thanks so much :)
Regarding PRL, the hypothalamus secretes both inhibitory and excitatory hormones that regulate prolactin secretion.
Thank you.
Thank you so much, you helped me lots!!!

Beautifully explained (:
🌿🧠🌿Thank You
Hypothalamus is part of the brain it's not a gland.
It is located near the pituitary gland and controls the release of hormones
0:17
Very interesting video.
Now, can you tell me how is it that the hypotalamus "knows" what to release?
Thank you.
It detects markers in the blood and releases the appropriate hormones. For instance, if it finds that testosterone is too low in a nigga's blood compared to the baseline level, it will release GnRH, which will trigger LH and FSH production in the anterior pit gland, which will stimulate the dude's nuts to produce testosterone. As for bitches, it's just swapped with estrogen and ovaries. Fact up, curry nigga.

amazing work
Thanks this the only vid I could find on the tropic non tropic shit
Well explained

well, did you find out?
I love you khan academy

sweet and simple :)
I need a video on the hypothalamic pituitary axis
awesome! helped me a lot
What about MSH melanocyte stimulating hormone??
Whats the relationship between the Hypothalamus and the pineal gland. Thank you.
Fucking FANTASTIC video. Best concise clear explanation of this topic I've seen.
What might cause an over-active hypothalamus?
If i could upload a meme here, it would be the meme of that asian guy squinting at a piece paper because I CAN'T SEE ANYTHING (anyway, good content keep up the good work)
I know a lot about other parts of the brain.
What's good for the Hypothalamus? How to strengthen it?

Awesome
hi? what are the hypothalamic neuropeptides?
thnx
What's the interplay between HPA , Hpg , hpt
Is it true that the hypothalamus is the cerebral cortex in the endocrine system?
What I am keen to learn is the reason why or how the hypothalamus knows which hormone it should release.

hypothalamus is a gland???
yes , it is actually the "Master gland ".

Healing glands so plz pray
i have a cyst in my pituitary gland
hypothalmus is a part of the brain not gland😱
if hypothalamus controls pituitary gland then why it is called Master gland?
Because pituitary gland regulates the activities of the glands
atleast 100 out of 3000 chemicals in cell used in medicine.
You have a good teaching way but your words are so tiny I can't read
Omg why does our body have to be so complicated, it sucks cos if one of our glands is sick or damaged we are not going to function properly.

I love these videos, but I cannot watch this one. The whistle of his "S"s is driving me insane. I only got about 30 seconds in. Ughhh.
You learn about the hormones ( i abbreviate as H.'s) then there more, more mor more more more
why two balls? immature designer, no?
both stopped working on me and now I pass out all the time and feel so sick .

If you didn't have a working pituitary or hypothalamus you wouldn't be able to type.
hypothalamus isn't a gland...
